SLOW QUERIES
The slow query log is enabled.
Current long_query_time = 3 sec.
You have 19 out of 4001623 that take longer than 3 sec. to complete
Your long_query_time seems to be fine
BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery
See
http://dev.mysql.com/doc/refman/5.0/...-recovery.html
WORKER THREADS
Current thread_cache_size = 64
Current threads_cached = 60
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine
MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 4
Historic max_used_connections = 110
The number of used connections is 22% of the configured maximum.
Your max_connections variable seems to be fine.
INNODB STATUS
Current InnoDB index space = 2 M
Current InnoDB data space = 2 M
Current InnoDB buffer pool free = 38 %
Current innodb_buffer_pool_size = 8 M
Depending on how much space your innodb indexes take up it may be safe
to increase this value to up to 2 / 3 of total system memory
MEMORY USAGE
Max Memory Ever Allocated : 683 M
Configured Max Per-thread Buffers : 2.56 G
Configured Max Global Buffers : 106 M
Configured Max Memory Limit : 2.66 G
Physical Memory : 5.81 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 8 M
Current key_buffer_size = 64 M
Key cache miss rate is 1 : 92744
Key buffer free ratio = 79 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere
QUERY CACHE
Query cache is enabled
Current query_cache_size = 32 M
Current query_cache_used = 19 M
Current query_cache_limit = 2 M
Current Query cache Memory fill ratio = 61.81 %
Current query_cache_min_res_unit = 4 K
Query Cache is 21 % fragmented
Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory
If you have many small queries lower 'query_cache_min_res_unit' to reduce fragmentation.
MySQL won't cache query results that are larger than query_cache_limit in size
SORT OPERATIONS
Current sort_buffer_size = 1 M
Current read_rnd_buffer_size = 1 M
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 2.00 M
You have had 533 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.
Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.
OPEN FILES LIMIT
Current open_files_limit = 2500 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine
TABLE CACHE
Current table_cache value = 850 tables
You have a total of 428 tables
You have 729 open tables.
The table_cache value seems to be fine
TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 9269 temp tables, 3% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Created disk tmp tables ratio seems fine
TABLE SCANS
Current read_buffer_size = 1 M
Current table scan ratio = 12985 : 1
You have a high ratio of sequential access requests to SELECTs
You may benefit from raising read_buffer_size and/or improving your use of indexes.
TABLE LOCKING
Current Lock Wait ratio = 1 : 59
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
If you have a high concurrency of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=2'.
